^ bitwise XOR operator

expression1 ^ expression2

Converts expression1 and expression2 to 32-bit unsigned integers, and returns a 1 in each

bit position where the corresponding bits in

expression1 or expression2, but not both, are

1. Floating-point numbers are converted to integers by discarding any digits after the decimal

point. The result is a new 32-bit integer.

Positive integers are converted to an unsigned hex value with a maximum value of

4294967295 or 0xFFFFFFFF; values larger than the maximum have their most significant

digits discarded when they are converted so the value is still 32-bit. Negative numbers are

converted to an unsigned hex value via the two's complement notation, with the minimum

being -2147483648 or 0x800000000; numbers less than the minimum are converted to two's

complement with greater precision and also have the most significant digits discarded.

The return value is interpreted as a two's complement number with sign, so the return value

will be an integer in the range -2147483648 to 2147483647.

Operands

expression1 : Number - A number.

expression2 : Number - A number.

Returns

Number - The result of the bitwise operation.

Example

The following example uses the bitwise XOR operator on the decimals 15 and 9, and assigns

the result to the variable

// 15 decimal = 1111 binary

// 9 decimal = 1001 binary

var x:Number = 15 ^ 9;

trace(x);

// 1111 ^ 1001 = 0110

// returns 6 decimal (0110 binary)
